Question

keanu is building a circular fire pit in his backyard. he wants to line the fire pit with stone pavers. if the fire pit has a diameter of 3.7 feet (ft), how many linear feet of stone pavers will keanu need to purchase? use 3.14 for π and round your answer to the nearest foot.

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $d$ is the diameter and $\pi\approx3.14$.

Step2: Substitute given diameter

Given $d = 3.7$ feet and $\pi=3.14$, we have $C=3.14\times3.7$.
$C = 11.618$ feet.

Step3: Round to nearest foot

Rounding $11.618$ to the nearest foot gives $12$ feet.

Answer:

$12$
